Demo Best Practice
Create a demo script with real-world scenarios from your manufacturing operations, such as handling a custom order, managing a production bottleneck, or processing quality control failures.
Check References and Site Visits
Contact existing customers of your top vendors, preferably in similar industries. If possible, arrange site visits to see the ERP in action in a similar manufacturing environment.
Key Questions for References:
- How has the ERP system improved your manufacturing operations?
- What challenges did you face during implementation?
- How responsive is the vendor’s support team?
- What unexpected costs did you encounter?
- If you could start over, what would you do differently?
Conduct Total Cost of Ownership Analysis
Calculate the total cost of ownership (TCO) over a 5-year period, including software licenses, implementation services, hardware, training, maintenance, and internal resource costs.
Make the Final Selection
Based on all evaluation criteria, select the ERP system that best fits your manufacturing business needs and budget constraints. Document the selection rationale for future reference.
Negotiate the Contract
Work with legal and procurement teams to negotiate favorable terms, including pricing, implementation services, support SLAs, training, and future upgrades. Ensure all promises made during the sales process are documented in the contract.
Contract Negotiation Warning
Beware of vendors who heavily discount initial license costs but have escalating maintenance fees or expensive “mandatory” upgrades in later years. Negotiate caps on annual maintenance increases.
Key Selection Criteria for Manufacturing ERP
When evaluating ERP systems for your manufacturing business, consider these essential criteria to ensure the selected solution addresses your specific operational requirements.
Manufacturing Process Fit
Ensure the ERP system supports your specific manufacturing type (discrete, process, mixed-mode, etc.) and production methodologies (make-to-order, make-to-stock, etc.).
A process manufacturer has significantly different needs than a discrete manufacturer. Choose an ERP with features designed for your manufacturing model.
Functional Coverage
Evaluate how well the ERP system covers your required functional areas, from production planning to quality management and warehouse operations.
Key manufacturing modules include MRP, shop floor control, quality management, and advanced planning and scheduling (APS).
Customization Capabilities
Assess the system’s flexibility to accommodate your unique business processes without excessive custom development.
Look for configurable workflows, user-defined fields, and low-code customization tools that don’t break during system upgrades.
Integration Capabilities
Evaluate how easily the ERP system integrates with other systems and equipment in your manufacturing environment.
Common integration points include CAD systems, MES (Manufacturing Execution Systems), PLM (Product Lifecycle Management), and IoT devices.
User Experience
Assess the system’s usability for all user types, from shop floor workers to executives, considering both desktop and mobile interfaces.
User adoption is critical for ERP success. Choose systems with intuitive interfaces that minimize training requirements.
Reporting and Analytics
Evaluate the system’s built-in reporting capabilities, dashboards, and advanced analytics features to provide actionable insights.
Look for manufacturing-specific KPIs, real-time production dashboards, and predictive analytics capabilities.
Deployment Options
Consider whether cloud, on-premise, or hybrid deployment best meets your technical requirements and business strategy.
Security and Compliance
Ensure the system meets your industry’s regulatory requirements and provides robust security features.
Consider requirements like FDA compliance, ISO certifications, GDPR, and data security standards relevant to your industry.
Vendor Stability and Support
Evaluate the vendor’s financial stability, industry experience, and the quality of their implementation and support services.
Ask about support hours, response times, escalation procedures, and available support channels (phone, email, chat, etc.).
Total Cost of Ownership
Calculate the total cost over a 5-year period, including licenses, implementation, customization, training, and ongoing support.
Don’t focus solely on initial costs. Consider long-term expenses and the potential ROI from improved operational efficiency.

- Create a formal communication plan to keep stakeholders informed
- Consider including external consultants for objective expertise, particularly if your team lacks ERP selection experience
Common Pitfalls to Avoid in ERP Selection
Many ERP implementations fail to meet expectations due to problems that begin during the selection process. Being aware of these common pitfalls can help you avoid costly mistakes.
ERP Implementation Failure Statistics
Fig 3: Percentage of failed ERP implementations attributed to these common causes (Source: Gartner, Panorama Consulting)
Focusing Only on Current Pain Points
Many companies select an ERP system solely to address current operational problems without considering future business needs and growth plans.
How to Avoid:
Create a 3-5 year strategic roadmap for your manufacturing business and ensure the ERP solution can support your future state. Consider potential business model changes, product line expansions, and geographic growth.
Selecting Based on Price Alone
Choosing the lowest-cost solution often results in missing critical functionality, inadequate support, or excessive customization costs later.
How to Avoid:
Consider the total cost of ownership (TCO) over a 5-year period, including implementation, training, customization, maintenance, and internal resource costs. Balance this against expected benefits and ROI.
Inadequate Requirements Definition
Many companies rush through requirements gathering, resulting in critical functionality gaps discovered only after implementation begins.
How to Avoid:
Invest time in a thorough business process analysis and requirements documentation process. Map current and desired future-state processes, document pain points, and clearly define both functional and technical requirements.
Choosing a Generic ERP Instead of Industry-Specific Solution
Manufacturing has unique requirements that generic ERP systems often don’t adequately address without significant customization.
How to Avoid:
Prioritize ERP vendors with proven success in your specific manufacturing niche (process, discrete, make-to-order, etc.). Ask for industry-specific references and case studies that match your business model.
Insufficient Stakeholder Involvement
Excluding key stakeholders from the selection process leads to resistance during implementation and limited adoption.
How to Avoid:
Create a cross-functional selection team with representatives from all key areas (production, finance, supply chain, etc.). Involve end-users in the evaluation process, especially during vendor demonstrations.
Being Swayed by Sales Demonstrations
Polished demo scripts often highlight strengths while masking weaknesses, giving a misleading impression of system capabilities.
How to Avoid:
Provide vendors with your own demonstration scripts based on your actual business processes. Ask for hands-on sessions where your team can test the system with real-world scenarios, not just watch a presentation.
Overlooking Integration Requirements
Many companies underestimate the complexity and cost of integrating the ERP with existing systems (MES, PLM, CRM, etc.).
How to Avoid:
Create a detailed inventory of all systems that must integrate with the ERP. Discuss specific integration methods, data mapping requirements, and potential challenges with vendors during the evaluation.
Ignoring the Implementation Partner
Many ERP selections focus solely on the software while paying insufficient attention to who will actually implement it.
How to Avoid:
Evaluate implementation partners with the same rigor as the software itself. Check references, review project methodologies, and assess the experience of the specific consultants who will be assigned to your project.
Case Study: Manufacturing ERP Selection Failure
A mid-sized electronics manufacturer selected an ERP system based primarily on cost considerations, without thoroughly evaluating how it handled their make-to-order production process. Six months into implementation, they discovered the system couldn’t efficiently manage their complex bills of materials with engineering change orders, requiring extensive customization that doubled their implementation budget and extended the timeline by nine months.
The lesson: Thoroughly validate that your most critical business processes are supported out-of-the-box or with minimal configuration. Don’t assume functionality based on vendor claims alone.
Calculating ERP ROI for Manufacturing
Calculating the Return on Investment (ROI) for your ERP system is essential to justify the investment, set appropriate expectations, and establish metrics for measuring success.
The ROI Formula
ROI = [(Total Benefits – Total Costs) / Total Costs] × 100%
For manufacturing ERP systems, this calculation should be performed over a 5-year period to account for the full implementation cycle and realization of benefits. A positive ROI indicates a profitable investment, with higher percentages representing greater returns.
Calculating Total Costs
When calculating ERP total cost of ownership (TCO), include both direct and indirect expenses:
- Software licenses or subscription fees
- Implementation services (consulting, configuration, customization)
- Hardware upgrades (servers, networks, shop floor devices)
- Data migration costs
- Integration with other systems
- Training expenses
- Maintenance and support fees (annually)
- Internal resource time and costs
- Productivity loss during implementation and adoption
Quantifying Benefits
Manufacturing companies typically realize ERP benefits in these areas:
- Inventory reduction (typically 10-20%)
- Labor productivity improvements (8-15%)
- Production efficiency gains (5-10%)
- Reduction in material waste (3-5%)
- Improved on-time delivery (10-50% improvement)
- Reduced quality issues and rework (5-15%)
- Lower administrative costs (reduced paperwork, automation)
- Better decision-making through improved data and analytics
- Compliance cost reduction

ROI Calculation:
ROI = [(Total Benefits – Total Costs) / Total Costs] × 100%
ROI = [($2,245,000 – $1,115,000) / $1,115,000] × 100%
ROI = [$1,130,000 / $1,115,000] × 100%
ROI = 101.3%
With an ROI of 101.3% over five years, this ERP investment more than doubles the initial investment, making it financially justifiable.
ROI Calculation Best Practices
- Be conservative in your benefit estimates; it’s better to exceed expectations than fall short
- Include all costs, even those that might seem indirect or “soft” costs
- Consider the time value of money by applying a discount rate to future benefits
- Break down benefits by department to create accountability
- Establish baseline metrics before implementation to accurately measure improvements
- Revisit your ROI calculation periodically after implementation to assess actual performance
